float x, y, result;

result = pow(x, y);

Compliant Solution

This code tests x and y to ensure that there will be no range or domain errors.

Code Block

bgColor	#ccccff

float x, y, result;

if (fpclassify(x) == FP_ZERO && islessequal(y, 0)){
     /* handle domain error condition */
}

result = pow(x, y);

...

Code Block

bgColor	#ccccff

float x, result;

if (isless(x, 0)){
     /* handle domain error */
}

result = sqrt(x);
